Abstract
This application discloses a display panel and a display device. The display panel includes a first metal layer, an insulation layer is formed on the first metal layer, a second metal layer is formed on the insulation layer, and a width of the first metal layer is different from a width of the second metal layer.
Claims20
A display panel, comprising:
- a substrate, wherein
- a first metal layer is formed on the substrate, an insulation layer is formed on the first metal layer, a second metal layer is formed on the insulation layer, and a passivation protective layer is formed on the second metal layer and configured to protect the second metal layer from humidity;
- a width of a bottom of each of the first metal layer and the second metal layer is greater than a width of a top thereof, widths of each of the first metal layer and the second metal layer gradually increase from the top to the bottom;
- and a width of the first metal layer is different from a width of the second metal layer;
- wherein each of both sides of a cross-section of the second metal layer taken along a width of the second metal layer has a gentler slope with respect to a surface of the substrate than the corresponding side of a cross-section of the first metal layer taken along a width of the first metal layer.
